Setup, Compatibility & Care
To ensure your card arrives in pristine condition, keep it stored in a cool, dry place away from direct sunlight, as intense UV exposure can fade the vibrant colors over time. When writing your message, place a spare piece of paper between the card pages to prevent any potential ink transfer if the card is closed while wet. Since this is a square card, check with your local postal office regarding mailing requirements, as square-shaped mailings sometimes require an additional 'non-machinable' surcharge in certain countries.
